摘　　要：以软基路堤拓宽工程——渔港路工程为例,分析软基路堤拓宽工程的路基沉降规律,根据分析结论,对该工程的沉降控制提出了相应的工程技术措施。结合工程施工期间及施工后路基沉降观测结果,对路堤拓宽工程的控制因素进行了验证。结果表明,针对软基路堤拓宽工程,可分别对老路路堤沉降控制、拓宽路堤回填区沉降控制、拓宽路堤原始地基沉降控制3个方面进行针对性设计和施工,能够有效减少软基路堤拓宽引起的不均匀沉降。Taking Yugang Road Project as an example,the settlement rule of road foundation in the soft base embankment widening project is analyzed.The relevant engineering technological measures are proposed for the settlement control of the project according to the conclusion of the analysis.Combined with the inspection results of road foundation settlement during the project construction period and after the construction,the control factors of embankment widening project are verified.The results show that aiming at the soft base embankment widening project,the targeted design and construction can be carried out for the settlement control of old base embankment,widened embankment backfill area and original foundation of widened embankment,which can effectively reduce the uneven settlement caused by embankment widening of soft foundation.
